I have created a C&C Online account and setup the username, email and password for the server etc.


When I boot Red Alert 3 through the C&C Online launcher and log-in using the Server Email and Server Password I setup earlier I get the error in the title.


"Cannot Connect to Backend Server"


Any help would be greatly appreciated. Essentially I have followed the steps here: https://cnc-online.net/en/setup/.

----- C&C:Online Launcher Start -----
Game: Red Alert 3
Red Alert 3 Install Path: D:\SteamLibrary\steamapps\common\Command and Conquer Red Alert 3\
Started game with: "RA3.exe "
Caught CREATE_PROCESS_DEBUG_EVENT from Red Alert 3. Detaching...
ERROR: game.dat process not found


This is what my Log File in %Temp% says.


I have tried running the game and C&COnline Launcher as admin and still have the same issue?

Hello ! Same problem here, i follow every steps but i can't connect to the backend server and this issue is not in the "Common Issues & Solutions" topic.


EDIT: Someone in the forums tried this and it works but not for me sadly


Steps: Go into the Windows Command propt (Windows+R)
Type: %appdata%
Click "Red Alert 3"
Click "Profiles"
Click: Your name user. ie. "Zayda41"

Click: Options

Delete the line: "FirewallPortOverride=0"
